Imagine using volumes to create a cloudy sky … ew.

 Summary

This Geometry Nodes/Shader setup generates a customisable sky background for your projects complete with clouds drifting in the wind. It is made to be as light on your PC as possible, although performance may be affected on older machines.

Simple Sky is super easy to use and an efficient way to craft clouds in the sky without breaking your workflow. It can be rendered in both EEVEE and Cycles. On a medium priced PC the viewport continues to play in real time (24fps)

How it Works

The basic premise is to generate a series of spheres around your scene comprised of 1 outer layer with the “3DN-SkyBG” material and 3 inner layers with the “3DN-SimpleSky” material. The “SimpleSky” material is essentially a fancy noise texture with transparency and a tonne of customisable options. This generates the clouds on the 3 inner layers. The distance between each layer creates the subtle parallax effect that you see in the real sky. The outer layer is a super simple colour ramp setup to make it as intuitive as possible.
